This advanced wall system has been independently tested and verified to deliver 360 minutes (6 hours) of continuous fire resistance under ASTM E119. It also withstood the rigorous ASTM E2226 hose stream test, demonstrating structural integrity after extreme thermal exposure. Constructed using 3B’s proprietary non-combustible material, the system offers reliable, maintenance-free protection for high-risk infrastructure.

Designed for demanding environments, the FR360™ offers one of the highest performance ratings currently available in the industry. Achieving a full 6-hour rating reflects the system’s robust engineering and its ability to withstand extreme conditions well beyond typical requirements. This level of performance provides an added layer of confidence for critical facilities where failure is not an option.
